JOHN G. .LOPATA, or BERWYN, ILLINOIS; V

wnmow.

To all whom it may concern:

Be it known that I, JoHN G. LOPATA, a citizen of the United States,residing at 2333 N. Winfield avenue, Berwyn, Illinois, have inventedcertain new and useful Improvements in Windows, of which the followingis a specification. i

The invention relates to windows, and has for its object the provisionof a window which may be quickly and conveniently detached from itsframe for cleaning, repair in or other purposes.

f further object of the, invention. entails the provision of awindowwhich normally is maintained in functional position 1n frame, but whichmay be withdrawn from.

said frame by a sliding movement whenever access to the window isdesired.

It is also an object of the invention to provide a window whichcomprises a rectangular frame containing a window-pane and an extensionhingedly attached to the sash, and which attachment holds the sash tothe window-frame so as to maintain the window in operative position. I

-It is also an object of the invention to provide the window-frame withan auxiliary verticalmember to constitute with .one of the uprightmembers of the window-frame a narrow opening through which the win- "dowmay be introduced and removed, as the case may be.

A further object of the invention aimsat the provision of a window-sashwhich has an extension hingedly attached thereto, and which extensionhas a plate secured thereto constituting an abutment, so that theextenth to which the window may be introduced through the narrow spacein the windowframe is limited and predetermined.

To the, accomplishment of the objects stated and others that will becomeapparent as the description proceeds, preferred embodiments of theinvention are described in the following specification, pointed out inthe claims, and illustrated in the accompanying drawings.

In the drawings:

F'gu're 1 shows in front view a window constructed in accordance with myinvention.

Fig. 2 is a side view of the in Fig. 1. g

Fig. 3 is a top plan View of the improved window;

parts shown angles to the member 7, for a particularly Specification ofLetters Patent. Patented June 29, 1920 Application filed August 30,1919.Serial No. 320,827.

Fig. 4: is a sectional plan view showing a window in operative positionin the frame.

Fig; 5 is a front view of a double window constructed in accordance withmy i11vention, with one window shown in operative position while theother is in a partly retracted or withdrawn position.

Fig. 6 is a section on the line 66 of Fi 5. fieferring to the drawings,1 generally designates'the frame of a window or sash comprising theupright members 2, 3 and the horizontal members 4, 5, adapted to receivea window-pane 6. In alinement with the upright member 3, a member 7 issecured thereto by hinges 8, 9. At the outer end of the upright member 7a plate 10 is se- 3, the sash Imay occupy a position constibe oscillatedto occupy a position at right purpose hereinafter further to be describeThe window-frame comprises the vertical members 12, one of which onlyappears in Fig. 4, and adjacent to one of said vertical members anauxiliary .vertical member 13 tuting anextension of the member 7 or" maya is provided, which, together with'the adjacent vertical member 12,forms a narrow space 14 through which the window proper may beintroduced. It is evident that in order to place the window in operativeposition, the windoufiframe 1 is introduced from the right to the leftthrough the space 14, as 'viewed'in Fig. 4:, until the cross plate '10'abuts with. the verticalmembers 12, '13

of. the window-frame. Subsequently the sash 1' is swung around thehinges 8, 9 to occupy a position in which'the opening 15 is closed. Toremove the window-frame for the purpose of cleaning the pane, or for anyother purpose, the sash 1 is first placed so as to form an extension ofthe member 7 and thereupon the operator seizes the T member 10 andwithdraws the same together with the member 7 and the window, whereuponconvenient access may be had to the window. i r

In Figs. 5 and 6 the invention is applied to double windows and as shownin this figure, one window is indicated in operative position whereasthe other window is partly withdrawn. The construction of the windows isidentical to that shown in Figs. 1 to' 4. The window-frameshown in Fig.5 has a window 16, constituting a transom and os cillatable about ahorizontal line given by the hinges 17 and 18. As far as this transom isconcerned it is of the ordinary construction and does not come withinthe scope of the present invention. The windowframe comprises thevertical members 19 and 20, the horizontal base member 21, theintermediate horizontal member 22, to which the transom is secured, andauxiliary vertical members 23, 24, arranged adjacent to the verticalmembers 19 and 20, respectively, for

the purpose of defining a space through which the improved, windows maybe introduced or withdrawn. Through the space 25, defined by thevertical members 19 and 23, the window comprising the sash 1, the

extension 7, and the cross member lO, may

be introduced. The identical window con-v structed of coursesymmetricalto the first named window may be introduced through the space26 defined between the vertical members 20 and .24 In the center ofthedouble window a vertical ledge 27 is provided whichat'the center isformed with means for securing the windows in closed position.

While the drawings disclose preferred embodiments of the invention, theyare merely indicative ofthe principle on which the inventionispredicated. It, is therefore not my intention to confine myself to thedetails exactly as shown, but I desire to claim the invention as broadlyas the state of the art permits.

I claim; 1. In combination with a window-frame,

comprising vertical and horizontal members,

an auxiliary member defining with one of said first named members anarrow opening, a sash containing a pane adapted to be introducedthrough said narrow opening, and means for securing said sash in saidframe and permitting said sash to ranged in functional position.

2..In combination with a wi comprising vertical and horizontal members,an auxiliary member defining with one of said first named members anarrow opening,

a sash containing a pane adapted to be introduced through said narrowopening, an

be are bers,'an-auxi1iary member defining with one of said first namedmembers a narrow opening, a sash containing a pane adapted to beintroduced through said narrow opening, an extension hingedly connectedto'said. sash, and an abutment at the free end of said 6X:

tension and of a width in excess of the width of said narrow opening. I

4. In combination with a window-frame, comprising vertical andhorizontal members, an auxiliary member defining with one of said firstnamed members a narrow opening,

a sash containing a pane adapted to be introduced through said narrowopening, a ban hingedly connected to said sash, and anabutment at thefree end of said bar and being widerthan said opening, said bar being ofa width sufii'cient to permit said sash to be swung into closingposition.

In combination wlth a window-frame, comprislng vertical and horizontalmem here, an auxiliary member defining with one of said vertical membersa narrow opening, a sash containing a pane adapted to be introducedthrough said narrow opening, a bar hingedly connected to said sash, andan abutment at the free end of said bar and being wider thansaidopening, said bar being of a width sufiicient to permitsaid sash tobe swung at right angles thereto.

6. In combination with a window-frame, comprising vertical andhorizontal members, auxiliary, members defining with said' verticalmembers narrow openmgs, aplurality of sashes each containing apaneadapted to be, introduced through one of saidnarrow openings, a barhingedly'com nected to each of said sashes, and an abutment at the freeend of said bar and being wider than said opening, said bar being of awidth sufiicient. to permit saidsashes to be swung atright anglesthereto, and said I i sashes being constructed to constitute a C10-ndowframe,
